Ladies tresses is another orchid that grows with Yadon’s piperia in the maritime chaparral of Manzanita Park. In the first photograph shown, ladies tresses is in the foreground, with a blooming Yadon’s piperia in the back left. The flowers of ladies tresses are white like those of Yadon’s piperia, but they do not have a spur and their petals cling together to form a short tube rather than spreading wide. Also like Yadon’s piperia, its flowers occur along a leafless stalk. However, they occur in separate columns that spiral up the stalk; this feature is most easily seen when the flowers are still in bud. Ladies tresses can be hard to distinguish from Yadon’s piperia when the plants are only in leaf. The leaves of Ladies tresses, however, tend to occur in more upright clusters of more than 2 leaves, whereas those of Yadon’s piperia are generally 1 or 2 and they lay closer to the ground.
